NITED STATES CHARLES M. LUNGREN, OF NEXV YORK, N. Y.

GAS-BURNER.

SPECIFICATION forming'part of Letters Patent Nd. 365,831, dated July 5, 18137.

Application filed July 31, 1882.

0 l whom it may concern.-

Be it known that I, Onnnnns M. LUNGREN, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification.

My invention consists in the novel construction and combinations of parts making up the improved gaslamp described in the following specification. The novel features and combinations will be more particularly described in the claims. i

In the accompanying drawings, Figure 1 is a longitudinal section of a form of burner constructed in accordance with my invention. Fig. 2 is a cross section on the line X X ofFig. 1. Fig. 3 shows a burner with a modified Fig. 4 shows a cluster of burners depending from a common pipe or chimney. Fig. 5 shows a flattened flame-tube with a number of gas-tips arranged side by side. Fi g. 6 shows a modified form of the transparent or translucent flame-tube. Fig. 7 illustrates another way in which a flame-tube suited to the purposes of my invention may be constructed.

Referring to Figs. 1, 2, 3, and 4t, Aindicates a pipe or flue, preferably of metal, forming an escape-flue for the heated products of combustion from the burner, and B an outer shell, be tween which and the flue A is a space for the passage of air to the flame.

The burner is of any desired form or construction, according to the shape of the translucent tube D with which it is employed, and may have a single jet or a number of separate jets arranged in proper relation to give a round, flat, or otherwise shaped flame.

The burner is supplied with gas or other inflammable substance through apipe, G G, a portion of which is preferably carried through or in close proximity to the escapeflue A, so

that the material consumed will be heated before reaching the burner proper. D indicates a flame tube or pipe of transparent or translucent material, and of any desired form in crosssection, connected at its end removed from the burner proper with the chiinney A. The end of the tube D near the burner is attached in any desiredmanner to the lower Serial No. 139,293. (No model.)

I end ofthe flue A,or to a lateral or downwardly projecting extension therefrom,or to any other desired support. This end of the tube is cut off from the chimney A by a diaphragm or partition, m, of any desired form or construction. Air is supplied to the burner E and the flame,'in whole or in part, through openings or from the space between A and B. This air supply is furnished to the latter space through openings 12 in the shell'B, and in its progress to the burner the air becomes heated by the products of combustion escaping through the flue A. The tube D might be flattened, as indicated in Fig, 5, and the burner E be con structed from a number of separate jets, or it might be circular in form and have an inner .tube or rod, as indicated at r, Fig. 7, so as to form-an annular flame-space, the buruer-jets being in this case arranged in a circular row, as indicated. The tube D may be made detachable in any desired manner, to permit light ing, or the burner may be lighted by applying flame at the mouth of the flue or chimney A. A division-plate, a, is located, as shown, in the space between the walls of A and B, so as to compel the air entering at the perforations p to pass indirectly to the openings at, and to thus be more thoroughly heated. The gas supplied to the burner is heated as it passes through the tube G. The gas-pipe G extends through a bracket supporting the burner, or itself constitutes the bracket.

Fig. 4. shows a cluster of burners attached to a common shell or support, 13. It is not necessary that the tube D should be wholly translucent. It may be translucent 011 one side only, or that in which illumination is de sired. It may therefore be made in the way indicated inFig. 8, where A indicates acupshaped piece ofglass, and B a piece of refractory material-sueh as porcelain, asbestus, or metal-secured in the cup so as to leave a tubular way for the flame.

It is obvious that abnrner of the hind described may be used in any desired position, and that it might be set upright or in position the reverse of that shown in Figs. 1 and 2, or that it might be turned and used in aposition ninety degrees removed from that shown. It is'therefore to be understoodthat the terms downw'ardly, upwardly, depending,

&c., as used herein, are not used in their absolute sense, but only to express the position or relation of the parts in a burner in the position shown in the drawings,'and I employ them as applying to any burner in which, if the burner be set in the position indicated, the relation defined would exist.

What claim as my invention is 1. The combination, substantially as described,of a curved transparent or translucent fiametube, a gas-burner above the flame-tube and adapted to deliver a jet of gas'intosaid tube in a directionsubstantially coinciding with the axis thereof, a chimney'or escapeflue'above the burner and flame-tube, and a connection between the base of the chimney and-the end of the flametnbe opposite that at which the burner is located.

2. A regenerative gas-lamp consisting, substantially, of a chimney or escape flue, a gasburner supported at or near the base of the chimney, a depending curved transparent flame-tube encircling at one end the gas-orifice and having its other end carried around for connection with the base of the chimney, and

air-passages for supplying air to the flame carried in proximity to the passages for the escaping products of combustion.

3. A gas'lamp consisting, essentially, of an escapefiue or chimney, a gas-burner located or supported at or near the base thereof, a depending curved transparent flame-tube, one of whose ends encircles the burner-tip, while -its other end connects with the base of the chimney,an air-casing surrounding the escapeflue, and an inlet-passage connecting the space between said casing and escape-flue with the end of the flame-tube into which the burner delivers the gas.

4:. The combination, with a gas-burner, of a transparent or translucent flame tube or pipe, an escape-flue or chimney placed above or at the opposite side of the gas-burner from the flame-tube, and a connection between the base of the chimney and the end of'the flame-tube removed from the burner, as and for the purpose described.

5. A gaslamp consisting, essentially, of a forked or branched tube forming the escapeflue or chimney, a gas-burner supported in one of the branches, a curved transparent flame-tube connecting the ends of the two branches, and a diaphragm or wall between the end oftheflame-tubeinto which the burner delivers thegas and the portion of the chimney through which the escaping products of combustion pass.

6. A gas-lamp consisting, essentially, of'an escape-flue or chimney, a'gas-burner at or near the base thereof, and a depending flame'tube connected at one end with the space into which the burner delivers the gas and at the other end with the base of the chimney, as and for the purpose described.

Signed at New York, in the county of New York and State of New York, this 28th day of July, A. D. 1884.
